Be lzno that l, E'owlinn ii. BAUER, a citizen of the United States, residing at Ohicage, in the county of Cook and State of Illi'- nois, have invented certain new and useful Improvements in .SrakeJEeams' of which the following is a specification.

In some railway car-trucks but little room sion element or member of the brake-beam well as those oi" the usual ..ion-rod, being received in -l sleeves on which the brakel are mounted. eonvexing or curving the web and flanges of such a channel-bar at its ends,that is, by pressing them somewhat into a rounded or convex, instead of substantially-rectangular, crosssic tion, the sleeve with an a tered aperture x-.1 be placed farther forward on the brake-imam, ecumi'imizing in the necessary space for the reception of the beam and its heads and their movements.

On the drawing, which forms apart of this speciliral ion, lhave illustrated the most desirable emhmlimcnt oi the invention; and, on the drawing, Figure 1 is aplaIn-viewol' the end portion of a bralcedir-am having my nproved conipressii'in mom her and sleeve; Fig. 2 is a topplanviowoi an end portionol' the com-- brossimr-bar; i s 3 is a lace ror'sidc elevation of the part hown in l ig Fig. r illustrates, on an onlai' ol' the coinprossiondmr at its Fig. 5 illustrates a cross-sect bar near its end: Fig. 6 is a, sW'l'iOil on line 5 and 6. The brake-beam is also sup lied with the usual tension-rod 12, the on s of which and the rounded portions 11 of the compression bar are received, as usual, in apertures of cylindrical sleeves 13, only one of which is indicated on the drawing. i

In. Fig. 7 I have shown in crosssection the style of sleeve 13 which it will be necessary to use if the ends of the channel compressionbar 10 were not. rounded, as shown in Fig. 6, the position of the rod 12 bein the same in each instance. Owing to the act that by transversely rouilding or curving the ends of the channel compression-bar the'parts most remote from the center of the tensionrod 12 are brought nearer to the same, the aperture or passa e in the sleeve 13 which receives the ends 0% the tension-rod and compression-bar may be arranged more concen trically, thereby bringing the center of the sleeve farther forward on the brake-beam. i have found that by l This advantage will be readily understood by a comparison of the constructions shown in Figs. 6 and 7, from the latter of which it is obvious that, owing to the greater distance from the center of the tension-rod 12 to the longitudinal edges 10 of the channel compression-bar, it is necessary to so arrange tlie aperture in the sleeve as to leave a considerable portion of the sleeve rearwardly of the web of the com ression-bar. It is just this arrangement anr disposition of the parts which my improved construction avoids.

it is to be understood that, although I have shown and described a single preferred embodiment of my invention, the invention is nevertheless not limited and restricted to the precise details of construction set forth, because these maybe varied within comparatively wide limits without departing from f the substance of the invention.
